In the article “Chronic kidney disease and prevalent atrial fibrillation: The Chronic Renal Insufficiency Cohort (CRIC)” (Am Heart J 2010:159;1102–7), the authors would like to correct errors in their article. The errors appear in the Methods section and in Table III.
The atrial fibrillation (AF) question mentioned under AF Ascertainment should be corrected as follows: “Have you ever been diagnosed with or has a doctor or other health professional ever told you that you have atrial fibrillation or atrial flutter (an irregular heart rhythm)?” The published text stops at “atrial fibrillation” with omission of “an atrial flutter (irregular heart rhythm).” The authors write: “While this distinction may not have had major influence on our estimated prevalence of AF, it is possible that the lack of specificity of the question increased the reported prevalence beyond what it would have been if the question had only asked about AF.”
The authors continue: “The odds ratios for the continuous variables in the first column of Table III are per 1-unit increase not per 1-standard deviation (1-SD) as in the rest of the table. The ORs and 95% confidence interval for 1-SD increase in age (year), total cholesterol (mg/dl), uric acid (mg/dl), hs-CRP (mg/dl), body mass index (kg/m2), and physical activity (total MET h/wk) should be 1.44 (1.30–1.59), 0.85 (0.77–0.93), 1.09 (0.99–1.19), 1.05 (0.96–1.13), 1.09 (1.00–1.19), and 0.77 (0.69– 0.86), respectively. The p-values associated with these ORs are stated correctly in the table. We apologize for any confusion or inconvenience this has caused.”
